Description

"In nuclear physics, the island of stability is a predicted set of isotopes of superheavy elements that may have considerably longer half-lives than known isotopes of these elements. It is predicted to appear as an 'island' in the chart of nuclides, separated from known stable and long-lived primordial radionuclides." - Excerpt from Wikipedia Article A group with variable purpose driven by the 115th element. Will eventually hold & host games. Disciples and above are reserved towards the specially recognized. For those worthy (Acolytes+), respect the unspoken role resonating within the community wall.

Growth

5 measurements spanning 19 days, net +5. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 447–454 and does not start at zero.
