The Elder Scrolls Online site has been updated with a pair of articles profiling both the Ularra battleground the Vvardenfell zone. The latter, in particular, is a primer of sorts for anyone not overly familiar with the lore and locations of the entire Elder Scrolls series and centers on political factions as well as the natural elements of the zone.
Morrowind, and Vvardenfell in particular, has a unique ecology unlike anything else seen in Tamriel. Separated from the west by the Velothi Mountains and further isolated by the Inner Sea, Vvardenfell has been shaped by volcanic activity and enjoys a mild, if often hot, climate. Red Mountain's lava flows and ash-falls provide a constant cycle of death and rebirth for the woodlands and mushroom jungles, resulting in a diverse set of flora and fauna. From the fungus forests of Zafirbel Bay to the swamps of the Bitter Coast to the ash dunes of the northern Ashlands, life not only finds a way to survive on Vvardenfell—it thrives!
Ularra battelground is set in an ancient temple that practically begs opponents to fight to control higher ground. The center is a wide open space that can be accessed by teleporter hidden away in the overgrowth surrounding the platform.
As with the other battlegrounds, players can play Team Deathmatch, Capture the Flag or Domination.
You can read more about each of these locations on the Elder Scrolls Online links provided above.
