White Dragons (not to be confused with Wight Dragons) are ice dragons and live in cold climates. They are fond of eating, sleeping on huge piles of treasure and joining bards on quests. Sharpe says sagely."Hail hairy one. I too have encountered those that refer to themselves as immortal and have sent them to Helheim. I have recently slain a goliath warrior of great skill. As for a dragon? I have never encounter such a creature, nor a lich. I harken from the land of ice and snow, the dragons would not do well in such a climate. As for your accomplishments, they seem many. A strong warrior you appear to be my good man" Sigarr replies, accepting the invitation.
"Ah, it appears that some has imbibed too much mead, unless you are Loki in disguise attempting to confuse me. I may not be Vor, but I do know we do not share any ancestry" he replies.
"Ah, it appears that my skills are needed. I shall accompany you on this quest and afterwards mayhap you shall help me" the brawny half-giant states, gathering his unique weapon and following the others out.
As for Loki, I never met him but I bet he would be fun at parties!
