Any date for Malchor's sculpting period?
1 BE The Gods give magic to the races of Tyria.
0 AE They split the bloodstone
Scriptures of Grenth, 48 BE
Thats about all I can give you thats remotely helpful and I realize it isn’t really helpful at all. I know there are a lot of people who know more on the topic and there is a rather large discussion somewhere on the GW2guru forums about Malchor and the gods.
There is some Malchor stuff in here:

Those two might interest you to read, although if you haven’t played GW1 or aren’t familiar with it’s storyline you might get a bit lost?
One of the “unfinished” Dwayna statues at his workshop in Malchor’s Leap is written in Old Krytan if I remember correctly. Which means that he was still sculpting Dwayna’s visage after Kryta was established and held its own language – though we don’t know when Kryta was established by Orr (it was settled twice – first by Orr while King Doric was king (100 BE to Year 0), the second was by Elonians in 300 AE).
Though this gives the indication that he was blind sometime after 100 BE.
The Scriptures of Grenth isn’t very helpful given how it might be that Malchor sculpting Grenth’s statue is falsified (the gods have a habit of doing this to cover up the previous gods – they did for Abaddon, why not for Dhuum? I mean, other than the Memory of Dhuum’s Last Stand, nothing predating knowledge of the events of Nightfall signifies knowledge of Dhuum in Tyria).
Alternatively, if Grenth was sculpted by Malchor, then he was likely sculpted while young (he does look like a young warrior in the Malchor statue after all) since it’s highly implied that Grenth is Malchor’s son.
But basically, we can only narrow it down to 100 BE to 0 AE for certainty, and from 48 BE to 0 AE for possibility.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
