Reverse 1999 Cornerstone banner is called The Future’s Foundation and ends on Thursday 5 November 2026 at 09:59 GMT. Its featured six-star character is Cornerstone (Mineral). The two five-star rate-ups are Diggers (Plant) and Desert Flannel (Beast).
Cornerstone also has a personal story, See You in the New World, which closes at the same time as the banner. Completing Main Story 1ST-16, Heaven Apostles unlocks access. Finish it for Clear Drops and growth materials even if you’re not planning to summon.
Reverse 1999 Cornerstone Banner: All Three Rate-Ups
The Future’s Foundation is the banner to open if you’re after Cornerstone. She’s the featured six-star Mineral character, with Diggers and Desert Flannel as its five-star rate-ups. Check all three names before spending pulls, particularly if other banners are on your screen.
| Rate-up character | Rarity | Afflatus |
|---|---|---|
| Cornerstone | 6-star | Mineral |
| Diggers | 5-star | Plant |
| Desert Flannel | 5-star | Beast |
A rate-up improves a featured character’s chance, but isn’t a guarantee that your next six-star will be Cornerstone. Tap Details on The Future’s Foundation to review its exact rates and guarantee rules before using your summoning currency.
When Does the Reverse 1999 Cornerstone Banner End?
The Future’s Foundation runs from 15 October at 05:00 to 5 November at 04:59 (UTC-5). Bluepoch uses a fixed UTC-5 offset; the closing time converts to 5 November at 09:59 GMT in the UK. The banner expires in the morning, not at the end of Thursday.
If Cornerstone is your target, open the banner while it’s live, check your current resources and the in-game Details, then make your decision before the morning deadline. Any progress towards guarantees depends on the rules shown for this banner.
How to Find The Future’s Foundation
Open the summoning menu and look for the banner titled The Future’s Foundation. Cornerstone should be displayed as the six-star rate-up. Check the named five-stars on its Details panel as well, especially if several event banners are active.
Reverse 1999 Cornerstone banner is not The First Drop of Rain. That older-character banner features Semmelweis, Mercuria and A Knight following the Version 3.8 update. Select The Future’s Foundation if you want Cornerstone’s rate-up, rather than pulling from the wrong character pool.
See You in the New World Story and Rewards
See You in the New World is Cornerstone’s personal story. It began on 15 October and runs until 5 November at 09:59 GMT. To enter, complete Main Story 1ST-16, Heaven Apostles, then look for the character story in the Version 3.8 events.
Complete See You in the New World through the Version 3.8 event menu for its Clear Drops and growth materials. The character story and the summon banner are separate, so you can collect the story rewards without making the story a substitute for pulling.
Reverse 1999 Cornerstone Banner vs The Temporal Scale
The main Temporal Scale story and Hard Mode finish on 2 November at 09:59 GMT, three days earlier than Cornerstone’s banner. The Plumb Line exchange shop stays open until 5 November, however, and several other Version 3.8 activities share that later date.
UTTU Scouting Trip: Unrecorded Legends also runs until 5 November and rewards a separate set of materials. See our UTTU guide if you have not yet cleared that event. A character story, a main event and a summoning banner should each be checked independently.
What Should You Do Before 5 November?
If you want Cornerstone, check the summon menu’s Details before spending and leave enough time to pull before 5 November at 09:59 GMT. For the personal story rewards, finish the available chapters and collect them by that same cutoff.
For Reverse 1999 Cornerstone banner, the key is the 09:59 GMT expiry. Don’t confuse it with the earlier 2 November main-event story deadline or the separate anniversary outfit chest. These offers appear during the same version but have different reward systems.
