Who stands where
| NPC | Station | What they unlock |
|---|---|---|
| Zhirelle | Entrance, behind the Beacon | Shell Bond, Memories, free Tiel / Proxima map marks. Week 1: turn in Mether's Severance here to refund Glimpse. |
| Milos | Gloom Siphon / Ova Nursery hall | Explains the siphon. Deposit Ova until Mether's Breath (fast travel) appears. |
| Franz | Tarforge chamber, north of the siphon | Installs Muradean Actuator, Obsidian Lathe, Etching Needles, Foundry Stone. Killing him unlocks the first four functions immediately — irreversible on this cycle. |
| Vratko | Left of the Tarforge stairs, from the Ova Nursery | Offers to wash your feet. Shell-specific lines; no progression item. After several washes the dialogue loops. |
| Merrick | East wing shop | Healing upgrades, Tarstones, weapon maps. Shop is closed until you fast travel to any Beacon and return. First talk often includes an Axe & Dagger map as an apology. |
| Louis | Beside Merrick | Merrick's Great Dane. Flavor, not a vendor. |
| Sester Genessa | West wing training arena | Infinite Seal from the parry lesson. Later her own Shell, after Sester Secundus and the Censer. |
| Ruk | Top of the elevator, north pad | Route bird. Hands map fragments in the world; here he points you at the north pad (Widow's Overlook) versus the south pad (Mammon). |
| Thestus | Top of the elevator, after you light the Extinguished Lantern with Gloombound Flame | Night Mode toggle. Does not disable trophies. Do not confuse with Slayer Seal. |
First-visit checklist
- Rest at the Keep Beacon. This is where Harbinger leveling unlocks.
- Talk to Zhirelle. Accept the free Tiel and Proxima marks. Do not spend Glimpse on extra Shell pins yet.
- Siphon whatever Ova you already hold with Milos. You need Mether's Breath before the world is comfortable.
- Find Franz and dump the Muradean Actuator from the prologue dungeon.
- Walk to Merrick, then leave the keep via a Beacon and return so the shop is live.
- Train with Genessa for the Infinite Seal when you want a parry tool. Untarnished Seal is still the default until that timing clicks.
- Optional: throne past Merrick for the Slayer Seal. Pickup only.
- Optional after Week 1: wooden wall near Merrick for Mether's Severance, then back to Zhirelle if you want a Bond refund. See change Shell / respec.
- Elevator to the roof. Speak to Ruk. Take the north pad to Widow's Overlook. The south pad is Mammon.
Hidden dungeon off Genessa's room
A marked wall in the dark corner of the training arena opens Desolate Keep — the respawning Grisha used for remnant farming, and one of the Blackmarrow Key routes. Full loop is on Grisha Remnants. Shade chests around the elevator still need matching Shells plus keys; see keys.
Community video: what happens if you defeat every Marrow Keep NPC
Unofficial player experiment. Use it only as a visual tour of where each NPC stands. Killing Franz, Merrick, or Genessa is a one-way trade on that save.

Frequently asked questions
Why is Merrick's shop closed?
It is closed on the first visit. Fast travel to any Beacon and come back. KeenGamer documents this as the unlock, not a dialogue option.
Should I kill Franz for instant Tarforge unlocks?
Community testing says killing him enables the first four functions immediately, and the four key items then convert to upgrade ores. It is irreversible for the cycle. This site still recommends collecting the items unless you accept that trade.
Where is the Slayer Seal?
On the throne past Merrick, overlooking the land. Picking it up is safe. Equipping it is reported to disable achievements on that save. It is also the key for the Desolate Keep Grisha farm door.
Can I respec Glimpse after Week 1?
Yes on PC once the Week 1 Update is installed. Mether's Severance is turned in to Zhirelle and refunds Glimpse spent on that Shell's Bond. Rock Paper Shotgun's keep tour places the item behind a wooden wall near Merrick.
