We have killed the Ach... Ar...thingy ages ago and probably the Emo-whatshisface too. Pretty sure about it. Well sure-ish.
But we are 100% sure that Koralon was downed in guildrun first time 19/10/2009 (along the other two).
And because we didn't have paladin in the group we got many paladin loots - grats us!
