With cardtexts, it's easier to answer:
Both happen "during your unlock phase", so you can order them as you want.
Name: Nocturn
Cardtype: Ally
Cost: 1 blood
Discipline: Obtenebration
Demon with 1 life. 1 strength, 1 bleed.
[obt] Move Nocturn to the ready region when recruited. If this is this vampire's first successful recruit action this turn, he or she unlocks. Nocturn can play non-ally cards that require basic Obtenebration [obt] as a vampire. Burn Nocturn during your unlock phase.
[OBT] As above, and this vampire may perform this action again this turn, with the cost increased by 1 blood.
Name: Khobar Towers, Al-Khubar
Cardtype: Master
Clan: Follower of Set
Cost: 2 pool
Master: unique location.
Lock during your unlock phase to remove a ready minion you control from the game and gain X pool, where X is the capacity of that vampire or the blood or pool cost of that ally.
