Gateway Glass

The Gateway Glass is a Hardmode mirror which can be used to set a temporary gateway and teleport to it. When right-clicking, the user will place a gateway, indicated by a star at that location. When the player left clicks, they will be teleported to the gateway. The gateway will be removed after either teleporting to it, setting a new gateway, or naturally after two minutes. Left clicking without a gateway set will not teleport the player, but will still consume mana.
