 1 'ABOM-SKELETON'
 "Ah, the simple skeleton. The first you learn. Despite their lack of brains, they
 seem quite... intelligent. They are able to wield weapons, and able to follow you
 through a portal. Despite this, hmm.. intelligence.. they are immune to all kinds
 of mind control effects. The proof that there is no brain in the skull.
 Oh, and I should mention this: They are very dedicated followers, and will willingly
 sacrifice themselves for your well-being."
