: I think the reason they "melt into shadows" is
: becauls they are so old that when they are finaly
: killed they turn to dust.
: The exsplosive skulls are heavey morter rounds I think.
: Some dwarfe was talking about them on "The
: Wall".
The skulls can't be mortar rounds. The skulls are powered by a mana bar on the krid giants (this means that they are magical). And the skulls are skulls. Mortar rounds are not skulls. There is a large difference between a bone structure and ball of metal and gun powder.
The dwarf was talking about the cannons that were firing from the walls of Muirthemne on the level of that same name (the zerk is arguing "but they were cannons!").
The turning to dust part seems kinda weird, but I'll have to give you that. You can't really tell if the goo that the giants turn into is black dust or shadows, so either one is equally believable.
