Major Agenda of Bellam - Essentially, to become a sovereign lord with no vassalage to anyone, ruling at least 4 provinces.
Unwritten Agenda of Bellam - DESTROY SWORDWRAITH!!!!!
This is a little complicated. Back in RoE 1, Brandon basically threatened/strongarmed me into choosing to side with Osoerde during the war with Aerenwe. Tristan, using the power of the Eye of the Serpent, a powerful dark artifact he'd awakened, compelled Aerenwe troops to 'assassinate' him, giving him the excuse to turn his coat. This began (continued, really) a long, DEEP hatred between Swordwraith and Bellamie.
By RoE 2, I'd decided to start really playing up the fact that Tristan wasn't wrapped terribly tightly anymore. One way I did that was deciding that he'd been claiming Swordwraith was responsible for the assassination attempt for so long, he'd come to believe it himself. He simultaneously treasured the memory of casting the blame on her AND blamed her for betraying and trying to murder him. As such, seeing her brought down really consumed him. Taking control of Aerenwe also seemed like one of my best shots at my main Agenda - Tristan was NOT well-liked by the other Barons of Osoerde, so trying to achieve independence within Osoerde seemed like a great way to get my head cut off. And since Swordwraith would want me dead forever anyways, it wasn't like I could piss her off any further. Once she angered one of her vassals enough to turn him against her, I figured I had my chance. I misunderstood Bjorn at some CRUCIAL moments, though, and kicked the rebellion off too early believing that my patsy was going to act with me or without me. I had plans to try and salvage things, but it wasn't looking great when the game ended. I figured I'd survive fine, but my dreams of ruling Aerenwe were getting thin. I had plans, although not certain ones, for how to force Osoerde to recognize or at least accept me (finding and killing/controlling the last of the Swordwraith children was a necessity), and I had some secrets that Osoer would not like getting out that might've worked to push on him, but NONE of my plans ever anticipated Ghoerean AND Avanil armies arriving in AERENWE to interfere! Oi....
Minor Agenda - get Dhoenel back. Would have come with Aerenwe if I'd won.
Minor Agenda - depose House Isilviere. Osoer ruined that plan systematically. Tristan was getting pretty pissed about that.
Minor Agenda - Improve my Guild Holdings. Working on it, but honestly, I found it way more boring than my other plans. Oh, well.
I was also working up some Agendas having to do with fighting the Shadow's plans in Anuire. Again, this is complicated.
One of the parts I got a real kick out of was that Tristan had been gaining power from several dark sources - he'd been empowered by the Eye of the Serpent and trained by a powerful wizard of both Shadow an Daylight magic, the son of the paladin over in the west, in Boer's lands. He was a master of Shadow Magic, effectively a level 11 sorcerer with it. Since several of his levels were as a Shadow Adept, he had power over the Shadow World's Seeming, over creatures of the SW like the undead and doppelgangers, and he could travel into and out of the SW with a fair degree of ease. It was very useful on adventures, and he eventually used it to lead a force of men into Calrie's castle, kill Swordwraith, and rescue Ardai (who someone, I assume Swordwraith - Milo, confirmation? - had mind-controlled). His powers were the key to most of his plans, but their very existence would see him burned at the stake if discovered. He actually revealed a lot of it to the old IHH pontiff, Royce, towards the end of RoE 1, believing he could escape too much punishment that way - plus he needed some help. Then Royce was murdered and Tristan began getting TRULY paranoid, especially as he learned Royce had been replaced with a doppleganger before his murder. (For the record, folks - the Iron Rider killed the fake-Royce. He enchanted Osoerdean troops into doing the deed for some reason, but he was the one responsible, having discovered that 'Royce' was serving evil now).
Anyways, Tristan worked hard to keep his secrets, but he knew people might still eventually discover at least some of them, so he began deliberately building a case for sparing him if it happened. He was working with Wallac and Osoer to hunt out as many of the Shadow's agents as possible and joined every adventure against Awnshegh or dark forces he could find, so that if people learned he had access to dark powers, he could argue that he was using them for GOOD! And he actually was, in half his mind - his mind had taken a lot of damage from the Eye, and he was quite capable of believing mutually exclusive things at the same time. But whatever his motivations or beliefs, he was constantly working for the cause of the Light in Anuire, and I think his contributions were pretty significant, although many of them were kept secret. Any time our parties went into the Shadow World, Tristan was constantly reshaping it to clear the way, creating or summoning guardians and allies to battle threats before they reached the party, and protecting the other adventurers from the SW's weirdnesses. He had power over the undead, which I think people got to see pretty clearly in the fight against the Wraiths under Ilien. And he was responsible for clearing Osoerde and a good half of Roesone, as best I can judge, of the doppelgangers. And so on. His guild contacts combined with his powers and his adventuring meant that he was putting together what i THINK would have become a decent picture of the forces infiltrating Anuire, although I never knew who they were serving.
I don't know that it would have saved him from various rulers or priests if they learned what he could do, but i think he could have made a good case that he was too valuable a resource to execute. But as long as I was doing it, I figured I could get some Agenda points for it.
