The Frontier Portal Cathedral

Cathedral at the end of the road

The Frontier Portal Cathedral is the massive stone structure at the dead end of the Frontier’s main road, distinguished by four colossal pillars radiating raw power. It is separate from the Demon Castle: the castle houses the court and dungeon, while the cathedral contains the portal route.

Return route

After the Demon Court’s punishment, Shun must painfully cross the Frontier to reach it because Magnus deliberately prevents a direct teleport. The portal’s hum guides him through the cathedral and back toward the Tower’s Gate chamber, where Roku maintains the no-passage order.

Built route between realms

The Cathedral is reached only after Shun crosses the Frontier’s main road in pain. Its massive steps, stone mass, four pillars, and portal identify it as a purpose-built threshold distinct from the prison architecture of the Demon Castle.

Courtly coercion

Magnus’s order that Shun cannot teleport directly turns the walk to the Cathedral into part of the sentence. The portal is the route home, but the route itself publicly demonstrates the Court’s power over the former hero.
