Alticorn of Idumea

The gods of good are frequently underestimated, where evil gods stomp around destroying all before them or brew evil schemes that reach across the planes their opposites much less dangerous. To think so is of course a foolish mistake.

The alticorn of Idumea is a living example that even the patience of the good gods has limits. It looks like a giant unicorn whose coat is red as blood. The gods call forth the alticirn when evil is entrenched behind great walls and within the strongest of fortresses, for the alticorn is a living siege engine who can tear apart these fortifications with ease.

Like any manifestation of the wrath of the gods the alticorn is frequently imprecise and heedless of collateral damage. As its mighty hoofs and horn tear apart the hiding places of tyrants all to often the oppressed are in just as much danger.

The alticorn of Idumea is more likely to function as a dangerous ally than as an enemy, though if you are playing an evil campaign the appearance of the alticorn can signify they have entered the big leagues, as a minor rebellion suddenly becomes a real threat to them.
The alticorn is probably best used when the players are still low level, making the great creature almost as awe-inspiring and dangerous to them as it is to their enemies. For high level parties however the alticorn can function as an ally or as a way into places they cannot otherwise get into.


Mythic Alticorns of Idumea are called upon when the greatest holdfasts of evil must be torn down. Their size is even greater and they can use mythic power to use mythic dispel magic on the target of their Wall Piercer ability before rolling for the attack.

The alticorn of Idumea can be summoned to do battle against evil with an occult ritual. This ritual requires several successful Knowledge (planes) and Knowledge (religion), as well as the cornestone of a destroyed caste of an evil lord. The summoner should beware though, for if summoned without just cause the wrath of the alticorn may fall upon them instead.

The PCs are sneaking into a city ruled by the villain when the alticorn of Idumea suddenly appears and starts tearing the city apart. The PCs now have to get innocents out of the way while also completing their original mission.
