Overworld 2 (old crystal sword)
Overworld 2 (old crystal sword) adds a second dimension reached through a portal frame, with a warning block and decorative blocks, for NeoForge 1.21.4.
What it does
A portal frame block opens the route into the Overworld 2 dimension. Players who step through the portal receive a regeneration effect on arrival, which applies while they stay in the dimension. The dimension is added as a new destination alongside the vanilla worlds, so a world can hold both.
The mod includes a warning block and a work-in-progress decorative block, both meant for building inside the dimension. Files exist for NeoForge 1.21.4 only, and the latest build is 1.0.8, published on 2025-06-03. The first release came out on 2025-04-22. Installation covers the server and each player's game. The code is covered by All rights reserved and is not open source. Public issue tracking is available through the author's links.
The author describes the mod as a world content addition that can be used in a modpack, and notes that a movie addon is planned for the future. Those plans are not part of the released files.

How it compares
Knightartorias7's Dimensions is NeoForge for 1.21.4, client and server, and All rights reserved, the same as Overworld 2. Tons Of Dimensions covers a wider range, 1.21.4 – 1.21.8, and is also client and server under All rights reserved. Nether Ores is server-side only on 1.21.5, so players need nothing installed on their side.
