Kreegan
The Kreegan are a nightmarish, alien-like race. If Alleron chooses this form, he obtains the View Past spell, which can only be cast while in Kreegan form. This spell is useful for seeing events from the past, and even obtaining items that would otherwise be unobtainable. This spell usually has some sort of reward if cast near a dead human character if said character was found dead and could not have been saved.
The grunt form is an eyeless beast with a mouth within a mouth, who moves around by rolling. Whenever one is killed, it likes to jump up in the air for some reason.
The shaman form is a floating blue winged creature without legs, who moves around by gliding. If Alleron upgrades to this form, he obtains the Bend Time spell, which is arguably one of the most useful spells in the game. Bending time slows down time for everything except the caster, which allows Alleron to easily break enemy attack patterns or give himself enough time to get away and recover.
The mage form is a purple floating creature with a huge head and is arguably one of the most dangerous characters in the game. It moves around with a weird glide, as it has to stop and push itself forward with each flap. If Alleron chooses this form, he obtains the Summon Kreegan spell, which is much like the Raise Dead spell except no dead creature is required. Alleron will simply summon a Kreegan warlord out of nowhere and that warlord will follow and fight to the death for him.
The Kreegan warlord is a large blue creature that runs around on all fours and has six bony spines sticking out of its back. Choosing this form grants Alleron the Silence spell. However, this spell is not recommended. Although it prevents enemies from sounding alarms and hearing Alleron approaching, it does not prevent any characters from spell-casting as the manual says. Besides, the Kreegan mage form essentially grants the Kreegan warlord form with it because of the Summon Kreegan spell.
