That's part of why he could still work well as an NPC, but I think that attitude could make him stand out as a playable character too. He and Ajna didn't have backgrounds in war, but they were both forced into combat in order to defend their homes. So, he obviously acknowledges the need to fight, but he still seems to maintain his ideals and even-tempered outlook despite the circumstances. I think it'd be nice to see a character like that, who can share some of Ajna's experiences from a mature perspective, play an active role in her journey. It's also kind of rare to see characters with Kaldi's qualities that are just plain, levelheaded, middle-aged adults, and not played off with quirks like the old sage, or the stoner, or the naive dreamer. He's chill, peace-loving and friendly, but still seems pragmatic and down-to-earth. Anyway, that's mostly water under the bridge now. Hopefully we'll get some more reveals soon so we can start toning down on the speculation.
