Just talked to Arantheal. And sometime in the previous few moments or even simultaneously Deus ex machina stated up.

Arantheal has told me to go to Old Dothulgrad with Keeper Sakaresh.

So...Fragments of the Past shows that my next subquest is to "support Old Dothulgrad". What does that mean "support"?

[+] question

And why isn't it showing on the map?

Deus ex Machina says I need to meet Calia if I recall correctly.

[+] main question

Is she Keeper Sakaresh? If not where is Keeper Sakaresh?

It's been a while since this post and most likely you have figured out your answers by now, but in case not...............

Arantheal asked you to support (meaning help with) the *excavation* in Old Dothulgrad because Lishari Peghast believes there might be hints there on how to build the machine to stop the cycle, or maybe even a prototype.

Calia is keeper Sakaresh. When you meet with her she will lead you to Old Dothuldrad. They don't show it to you on the map because its an essential part of the narrative that you meet Calia first and go there with her. So to prevent you from deciding to go there on your own, the devs don't show it to you.
