Dialga
Dialga is summoned at the Space-Time Altar inside Spear Pillar. The same structure is used for Palkia, but Dialga requires an Adamant Orb and produces the Temporal Flute.
How to Obtain
If Spear Pillar has not already been found, craft the radar shown below from one Water Gem, one Compass, one Clock, one Steel Gem, and one Poke Radar.

Use the radar search or explore Cold Shrubland, the biome named in the bundled Spear Pillar structure file. Identify the large ruined stone platform shown below.

Find the central altar and interact with it while holding the Adamant Orb. Confirm that the orb is displayed before using the Red Chain.
Use the Red Chain on the altar after placing the orb. The sequence consumes the chain, summons level 70 Dialga, and replaces the Adamant Orb with the Temporal Flute.
Keep the Temporal Flute. It is a required part of the later Arceus path.
