Unholy Jotuns!
You burned Caelum's millenarian library with its unique sum of holy knowledge, and you confess conducting unholy researches with hideous Gygjas in our most refined Citadel of Frozen Crystals. Who knows if you don't use captured Caelian virgins for your perverse rites!!!
These are definitely your ultimate sins, don't be surprised if civilized Nations take steps against you!
If you think this is too much for your poor Giants, give me back my capital and all territories once administrated by the wise rule of the Seraphs, and you -might- receive our forgiveness.
