Lith and Solus moved on the ceiling, slipping from one crack to another to never create a patch of darkness large enough for the skeletons to notice.
Strider and Ryka, instead, moved below the ground without producing a single vibration. The only issue with the Titania's means of transportation was that with only Earth Vision to sense her surroundings, she had no idea where the next safe area was.
She moved slower than Lith to make sure the undead wouldn't notice them and give the Tiamat a head start. Once Lith reached the other side of the west corridor and reverted to his human form, Ryka took it as her cue.
She dug her way to him and emerged a few meters past his position, just to be safe.
'How did you escape detection?' Solus asked. 'The arrays protecting the area were supposed to pick up the alterations in the ground.'
