This one’s more for new players to comprehend what exactly is going on when they read the “Contract Locked” tooltip.
I’d recommend changing “…fulfill the ambition…” to -> “…fulfill an Ambition…” so that a newer player, and the audience that this tooltip is aimed at, would understand clearly that an Ambition is a major element of this game that they need to be focused on, and not just a sort of typo.
P.S.
I’d also recommend capitalizing, italicizing or bolding the word “Renown”, so that the reader also knows that this is a major element of the game too.
