Thanks for sharing, Anwar! I look forward to seeing more of this later.
The Vulcans would actually be at war with the Andorians, which would explain the strained relations with Earth and their desire to keep them from further exploration since they either don't want the Andorians to gain a new ally or to further divert resources to guarding Earth from attack.
Don't forget, we don't have to keep the tensions between Earth/Vulcan and Vulcan/Andor (though we can if it serves to make a better story). No reason we can't heep it, though, if we want it.
