[@Klomster] Just treat the bombardment/Desolation of Tenohexotl as the Hiroshima and Nagasaki of this RP; everyone dropped the most devastating and explode-y WMDs on the planet to both destroy it but also to show off to everyone else "this is what our WMDs can do, don't fuck with us" sort of thing.

Basically, any weapon that didn't destroy the crust or stripped away the entire atmosphere was probably dropped on Tenohexotl as a sort of military show and tell amongst everyone else and was a decent place of testing stuff out. Hell, you could probably still get away with detonating shit on it provided you have a base on remains of Tenohexolt and don't destroy the planet entirely.
