Which Coruscant Tier is the Endless Dunes Gate

[Carmelita]

The question is in the title, but to clarify, both the portal to the Nexus and the portal to the Vasty Deeps are on Tier One. I was wondering if the Endless Dunes Gate was on a lower tier, providing a backdoor into the city, or whether the lower tiers only outside access was through Tier One.

All of the Gates are on Tier 1.
