ESO Thieves Guild Questline Boost

It's the first major new Thieves Guild story in nearly a decade — 8 quests centred on Quen's effort to build a guild chapter in Daggerfall while navigating rival gangs and the Koldane Cartel. The writing leans into classic TG themes: stealth, heists, planning, and avoiding bloodshed. It has no level requirement, costs nothing beyond the base game, and connects naturally to the existing 2016 questline without requiring it. Buy ESO Thieves Guild Questline Boost to clear the full chain in a single piloted session.

• Quen's Heist Attire — exclusive Season One costume, deterministic reward from the story;
• Prowler's Talisman fragments — new mythic item fragments unlocking across the 8-quest chain;
• Questline achievements — all story milestones completed.

Full Completion adds Heists and thieves troves, earning 3 of 4 Rogue's Refuge house fragments on top of the above. ESO Thieves Guild Quest Boost at BoostRoyal covers both options.

A new player house introduced in Season One, unlocked by collecting four house fragments:

• Wherenow Code Key — quest 4 of the main questline;
• Mysterious Nocturnal Note — Heists reward coffers;
• Baffling Baan Dar Note — thieves troves;
• Indecipherable Sai Note — outside Thieves Guild content, not included.

Full Completion covers the first three. All four should be collected before October 21, 2026. ESO Thieves Questline Boost at BoostRoyal includes the Full Completion option at checkout.

The questline is permanent — ZOS confirmed this at launch. There is no deadline to start or complete it. The Rogue's Refuge house fragments, however, have seasonal context — collecting all four before October 21, 2026 unlocks the house during the current cycle. If the house is not a priority, there is no urgency to order. ESO Thieves Guild Questline Carry is available now and delivers the same rewards regardless of when you place the order.
