Do lower level void shards matter at all?
since I'm running out of space with the two from area 42.
Nope, they are direct upgrades on lower-tier shards and you can't double slot the same shard. Once you obtain a higher-tier shard you can dump the lower tier. Shards of the same type and tier can be combined to increase the resonance level.
Haha, well it certainly looks nice
