I was vaguely inspired by the Lichs of D&D or the Russian legend of Koschei the Deathless.
His death is inside a needle, which is inside an egg, which is inside a duck, which is inside a hare, which is in shock
(In russian this joke sounds better, I swear) Would have been an interesting quest/boss fight))But that's probably not for chrono universe.
Back to the topic. Nice touch there with puzzles in Kasmir's castle. Ozzie is always in a jam *laughts* That's his bad luck...Hm...i wonder, what has happened to the mystic trio in this restored timeline? I guess, they never appeared on the stage in 605.
