Zeal
Zeal is an alphac-era PvP spawn world accessible via a portal in Babel.
Overview
The Zeal Portal in Babel (at -115, 66, 585 and -114, 70, 639) was labeled "Zeal Portal (PvP Spawn World)" — indicating Zeal functioned as a dedicated player-vs-player arena or zone separate from the main alphac overworld.
