There are heavy rumors that StellarDawn is the new name of MechScape. What that means is that no other alternative rumor is heavier.
The problem with Mechscape's new name being StellarDawn is that Andrew Gower recently said that he is unable to release the new name of MechScape. What that means is that the new name is a guarded secret even now. Then again, maybe Andrew Gower is assuming that we don't know about stellardawn.
