As per the GENERATION X limited series, Marrow's current status is that she has been depowered, while retaining the physical attributes of her previously mutated state.

The note at the end of the entry should read as follows:
Namor once experienced a vision of Merlin's origins where Merlin was a solar priest under the father of Igraine circa 10, 000 BS. Since this seems to be at odds with most accounts, the vision was presumably a delusion, fabrication or possibly the origins of an aspect of Merlin other than the Otherworld or 616 versions." …Thanks to John McDonagh for pointing this out.
The world Moto should have been included under Dominant Lifeforms.
