Soulframe is a free-to-play third-person action RPG developed by Digital Extremes, the creators of Warframe. It is set on the isle of Midrath and focuses on melee combat, exploration, and co-op play.

Preludes is Digital Extremes' name for Soulframe's current pre-alpha phase. It's an early, evolving version of the game that players can experience as it's built openly alongside the community.

Preludes 15

Siege of Fort Curlail

Q: What are Sieges in Soulframe?

Sieges are structured PvE events in occupied forts on a ~3-hour cycle. In Preludes 15: **Mirifuir** (Espadarte, Silistavf), **Fort Kearnhold** (Dewelion), **Fort Curlail** (runes and mats), plus **Turret Jotar** siege. Burn the Ode Skylantern to claim rewards.

Q: Which siege drops Espadarte fragments?

Siege of Mirifuir rewards Espadarte and Silistavf fragments. Siege of Fort Kearnhold rewards Dewelion fragments (burn the Skylantern after Castellan Malrog). Fort Curlail rewards runes and materials such as Corrupt Onyx and Crypt Keys — Avakot wiki does not list weapon fragments for Curlail.

Q: When do seasonal events like Festival of the Circade run?

Seasonal events such as Festival of the Circade return on a patch cycle inside the Crypt of the Circade. Check the event page for the current window and link to The Circade boss for Gossamer Quartz and exclusive armour.

Q: What is Hark, the Collector?

A world event on a ~6-hour loop. Pick it up at a World Tree Votive Shrine or find it in the overworld, clear Sinecure waves, then defeat the Nimrod or use a Thunderstone in the animal cage. See the Hark, the Collector event page for representative drops.

Q: How do Bita's Eve and Thawtide work?

Bita's Eve is the Halloween-style window for Wintersquash Seeds (smash squash props, defeat Tattie-bogles). Thawtide is the Dendrit Longnight festival at Tuvalkane with Thawtide's Plenty shop stock and Seeder crafting. Both are patch-timed — confirm dates in-game.

Q: What are Votive Mini-Quests on the Events page?

Short one-time mini-quests — eight on the Events index matching Avakot's Mini-Quest list: A Birdie Flown, Burning Sage, Deadwood, Laid to Rest, Lightning in a Vial, Mistress of the Thread, Runner of the Rose, and The Fungal Lord. Only some start at World Tree Votives; others begin from notes in villages or the College. None are repeatable 3-hour sieges.

Q: Is Soulframe free to play?

Yes, the final version will be free to play. During Preludes, access is available via weekly invite emails or by purchasing a Founders Pack.
