Ohm's Lab And Gale's Tomb?

So I often see the phrases Ohm's Lab and Gale's Tomb repeated on the forums, what exactly ARE they?

 

Ohms and Gale are a mystery on Wynncraft. Gales Tomb is behind the hive but the actual grave has hopper under it to throw items in. No-one knows what to put in the grave to unlock a secret entrance yet.

 

Well the item to throw into Gale's grave isn't released yet.

gale is a floor boss in qira's hive which is gavel's version of the tower of ascension.
there are a couple of weapons in the game referencing gale and ohms and telling us they were a couple with an unknown backstory

 

Ah, thank you! I've only completed the thunder floor so far.

 

I've found many secrets that could lead to Ohm's tomb, or stuff related to him. At the moment I am gathering info.
