Fertility sounds like Life
Unity sounds like Gravity, like Chimera.
Majesty sounds like Light; leadership as the main theme, monarchs tended to claim "divine right", etc.
Integrity sounds like the right one, since it matches Earth's theme of structure.
And what would the differences be between upped and unupped shards?
I meant the other shards' effects when Fertility is played. Will an upped SoR have a different effect than an unupped SoR when Shard of Fertility is played?
Quite easily the stats of the Shard Golem produced.
