Forum:How does protoss warp work exactly?

I know that protoss get their buildings and units from Aiur, but is their a specific place that buildings are warped out? if so, then why would the protoss need to get to a warp gate, to escape from Aiur after the zerg took over their planet. Couldn't the Dark Templar just have built some gateways on Shakuras to evacuate Aiur with? While I'm on the invasion of Aiur, how would the protoss get buidings from Aiur if the zerg took it over? And when Tassadar and crew turned on the conclave, then where would they get their buildings from now? And how do zerg bend time and space? Why do I have so many questions? ahh, help I don't know lots of things!!
