The accord was for Runescape gold to acknowledgment Saradomin's babe to him (that Zaros believes is currently captivated earnest by Nex), however if Seren's absolutely revived, she is pre-empted this and has her elves yield her from Nex instead.

So Zaros can disengage Seren's alterations to the alliance all he desires, but it doesn't alter the truth that Seren's faction's currently the one who gets Saradomin's daughter, so she's the abandoned one who can acknowledgment her to him and fulfil the pact. Thus Seren wins that you either way.

And Zamorak has a modified accord entirely. Together with Cheap OSRS gold and Saradomin's pacts, neither bisected was accomplished yet. Giving Zaros the Bedrock comes aboriginal for both of them, and afresh Zaros plays with his action -- something that Seren can footfall in and above.

But with Zamorak, it's the added way round. Zaros was the person who performed his activity first, in bold the last ritual at Children of all Mah. And so that the pact's already bisected complete by the time of Endgame.

There is annihilation for Seren to return more than Zaros, because he's done his bit. She does not even try, otherwise or adequate. All that's larboard is for Zamorak to play his allotment -- and about-face over the Stone.
