This unit contains a large fluid router array. By establishing an alternate data route to CONCORD networks, it grants de-facto administrative control of the system it's in to its owners. The Territorial Claim Unit declares to all of New Eden that the owning alliance intends to enforce their will upon this star system. Whether other alliances respect and defer to that claim is another question entirely.
To declare your alliance's Sovereignty over an unclaimed system, deploy the Territorial Claim Unit close to a planet and activate an Entosis Link on the TCU until your alliance has full control.
You must be a member of a valid Capsuleer alliance to deploy and/or take control of a TCU. A maximum of one TCU may be deployed in any star system. TCUs cannot be deployed in systems under non-Capsuleer Sovereignty. TCUs cannot be deployed in Wormhole space.
