The Japanese name of Priam, and a direct reference to the beta for Path of Radiance.
Paris
This unit was added as part of a special event for top-ranking Choose Your Legends results that didn't make the top 4, and contains a special voice line only in the English audio track, directly referencing a community meme.
Dorcas
An incorrect text pointer on this S-Rank Bow's description leads the player to assume it has a Brave effect, leading to perhaps the most common rom hack change of all time.

This legendary weapon exists in the data of Thracia 776, but it warns you: Cheating is bad!

Demon Dragonstone or Mage Dragonstone
A concentrated botting campaign got this noncombatant from Path of Radiance added as a Grand Hero Battle.
