Specimens in the northern damp-zone designated Eurajoki have completed a vertical shaft 433 units into stone older than their planet's current arrangement of continents. Into this they intend to place the spent remnants of their primary heat-generating ritual, then walk away for 100,000 orbits.
The Dornhaver Institute for Long-Duration Promises rates the average biped attention span at 5.2 standard frustrations before reassignment. The proposed sealing duration exceeds this by a factor of approximately 18 billion.
One specimen, Lauri Parviainen, explained the containment method to assembled note-takers: copper tubes, packed in wet clay. "So if the bentonite stays in place, we are safe," he said, in the tone these creatures use when they have decided a sentence is finished.
A second specimen, Jarkko Kyllonen, has personally assessed risk scenarios stretching one million orbits forward. His written civilization is roughly 5,000 orbits old. He reported the assessments as "positive".
The cost is listed as one billion of their trade-tokens. The substance inside will glow harmfully for a period during which the species is statistically unlikely to remember which hole it used.
