An elder lich recently returned from a journey across the worlds who seeks an artifact of ancient times.

A great bird so rare (according to some legends only one exists), that with its high intelligence and uniqueness it deserves the status of an NPC.

A less-traditional NPC, a magical creature, formerly a tree. Might function as a druid or hermit.

A mighty tree it was, giving shelter to wanderers and many birds, until one night two dragons battled on the sky, right over him. Their motives are unknown, but the loser fell to his death on the tree, and that, broken and burned with the acidic blood of one and the fiery breath of other become what it is now.
