The giant phase whale skeleton was a tantalizing but confounding find.
On one hand, its exceptional hardness and origin meant that it could probably be used to build exceptionally tough and strong assets.
On the other hand, the skeleton was mysteriously suspended in the middle of the giant cavern while remaining absolutely unassailable.
If the giant phase whale or whoever set up this tomb arranged all of these additional protections, then profiting from this find might be harder than everyone thought.
This was why Ves and many others were hesitating whether they should expend a lot of valuable resonating exotics just to open a giant portal.
Assuming that it was not possible to break apart the giant whale bones into more manageable pieces, the portal needed to be substantially larger than a mech. This required the usage of a much greater quantity of resonating exotics!
