Seahorses

It is unknown what motivation the seahorses have in waylaying ocean travelers, but it is certain that they can be powerful opponents. Capable of hurling mystic bolts of energy across the waves, these enchanting creatures glow with magical power.

Once a group of seahorses is spotted, it is probably best to stay clear and avoid inadvertently upsetting them, as they are sometimes seen accompanied by nixies.

Seahorses first appeared in Ultima IV as non-evil creatures, and again in Ultima V as slightly more aggressive. They disappeared without a trace afterwards.

As expected, they are normally found only at sea, but a friendly seahorse, Blissful, can be found in Cove in Ultima IV.

Runes of Virtue
In Runes of Virtue, seahorses peacefully swim the seas and dungeons of Britannia, friendly towards the hero unless attacked. Upon receiving any physical or magical assault, seahorses will launch into a violent frenzy and hurt magical balls of energy towards the hero while darting rapidly about. Beware the angered seahorse, for it is one of the most fearsome creatures in the land.
