team arenas?

This might sound stupid... I've beaten the game twice but i never pay attention about team areans. I know it is for pvp battles but I don't know how to unlock it. I have 3 areans on my map so far, as i remember, I talked to the gate keeper and he'll bring me into the pvp areans. But then, there's not always a gatekeeper to open the gate. For example, after I ascended and reached the dragon lair. I talked to the gatekeeper and he didnt bring me to hall of heros. Does anyone knows what I should need to do to unlock it? and I saw there's some pvp areans on an individual islands. Do you know where to get those areans? I went to ring of fire, ember camp and cant figure it out where to unlock it? Can someone help me please!!

you have to work your way through the Tombs to get the HoH

Next to Draknars Forge are the "Team Arenas" for LVL20 players. Go to DF and next to Vanyi (and the storage agents) you can zone into the arena. After that, it should be available as a marker on your map next to DF.

Tombs are from Dragons Lair. Go to DL, zone into the Tomb of Primeval Kings and play from there. It'll be a marker also on your map. You need to win a few matches in the Tombs before getting to the final "map" in the tombs... the Hall of Heros.

can you have a team in the ascalon or yak's bend arenas? Like can you form a team and walk in?

Thank you so much, I'll try it tonite.
