Since it seems like those coffins may very well be stasis pods for Mhachi survivors I can see him going there so that he can feed on the sleeping Mhachi dreams. It's in his best interest to keep them alive; hence all he'll have to fight us to protect his "cargo" atleast that might be one of the reasons.
That's apparently his shtick. Still, the Mhachi summoned the Void Ark at the end of the War of the Magi, a time period in which Diabolos was probably already sealed inside the Lost City. While it's still possible, I don't find this likely. Causality and all that. Diabolos might be using the suspended Mhachi voidmages that might be in there, but that's just a convenience he didn't set up.

I suspect he might end up being the 3rd/final boss for Void Ark 2 many months from now.
The Void Ark is going to be a "one and done" type deal; that is, there will be no Void Ark 2 or 3. Just the Void Ark. It's more a sky pirate thing than a Mhachi / Void Ark thing.

Doesn't rule out the possibility of Diabolos reappearing, but there is no Void Ark 2. Or 3. Or 12.

Also, I do believe that Void Ark may very well have been an Alagan vessel that was retrofitted by the Mhachi. Afterall, it does have a somewhat Allagan design. But most importantly, I am sure the 5 Astral Era civilization knew about Allagans, maybe even more than modern Eorzean since they're only 1 Era away from the Allag's golden years
Possible not probable. While it superficially looks Allagan, beneath the surface it's anything but. Aside from the bio-tech vibe compared to Allag's magitek, it's black compared to Allag's love of chrome. We've also been told that the Void Ark was summoned in desperation by Mhachi voidmages to escape the calamity that ended the war... though that's just a rumor.

The 5AE civilizations almost definitely knew about the Allagans, given they weren't around too long ago and they left crap everywhere. Still, I don't get the feeling the Void Ark is a retrofitted Allagan vessel.
