The ship is the Galyiam, a 800m long ship looking approximatively like this:
But more round and with ovale-shaped heavy containers under each wing, containing necessary supplies for geneforming.
(geneforming: process of modifying a planet and its native species in order to obtain a desired race)
It is not a warship, but it is not unarmed. Main weapons are two antimateer hypercannons (firing 1ton antimateer shells at faster than light speed, effecively hitting ennemies instantly from billions of km away), and thunder-plasma point defence (turrets use a beam of charged particles travelling at lightspeed to focus a plasma pulse on target. it's rather short ranged but very precise and do heavy damage on small target).
The hangar bay (hanging under the ship) host unarmed shuttles and a handful of drones (the drones are essentially two cylindrical motors with a small quantic matricial computer in the middle, plu four thunder-plasma and eight antimateer missiles as armament.)
It is quite sluggish in sub-lightspeed, as expected from a mostly civilian cargo of this size, but no threats are expected this far from
the frontlines. all known interstellar travel-able species.
The great lines of the desired race have been set by the Consensus:
-Protectors, not agressors. They should be adepts of preventive strikes, but avoid full-scale annihilation if not necessary.
-Unable to agress an Ataqalaa, for whatever reason.
-Obedient, yet able to take decision by themselves. They should be able to wage war by themselves.
Otherwise each ship is free to design the race they reckon being the most efficient. Consensus will choose between successful projects.
