perhaps a new artifact needs to be introduced into the family of terraformers and expanders

Defensive Grid: +1000 Passive Attack/Defense/Cloak
Maximum up to 15000.

Costs 43 GP also carried by T.O. Troop Carrier

This idea i like tho I'd rather not put it on a T.O. Troop carrier and there is the new npc that drops the +100 that you can use however you want. So it is already there tho i like the 1000 idea.

Dyson/exotic planets that you manufacture recently got SERIOUS upgrades, I believe it's 10K Atk/Def/Cloak. I do like the idea of a nbew NPC that drops expanders though. Maybe a K'rsp Krrrm Raider?

this artifact would mainly be for those ppl who want protection for their gaia, crystal, and sentient planets. It could also be used to bump up the defence of those exotics and dysons just a bit more.

Then your topic is flawed.

i suppose. they can also be used on dysons and exotics. the current passive abilities are 10k each, and this would put em up to 15k each. but they can also be used on 'prized planets'. perhaps i SHOULD change the topic title, but then again more ppl read it this way.
