Eridan’s design from Blackbird.
Eridan much like the rest of the cast as matured past his 13 year old self. Hes no chasing quadrants anymore and in fact hes filled a few(?). He serves as Feferi’s highest commander in her gathering army. Their planned coup of the Condesce is sweeps in the making.
While his matesprit, her royal heiress highly dislikes the Arenas and Gladiatorial combat, Eridan much enjoys it. There is a box in the amphitheater expressly reserved for His Majesty the Royal Consort. Strangely enough, it seems that Eridan is always in attendance of the matches in which the human Strider participates in. Always.
There is a curious rumor among the Highbloods that Strider is responsible for Eridan’s broken horn, made impertinent by the infamous knife made of troll horn the human carries hidden in his sash.
