Meet Cynthia, receive HM01 Cut, unlock the Underground Kit, and prepare for Eterna Gym without entering Galactic HQ yet. This standalone section joins the route plan to the original Diamond/Pearl map, encounter, trainer, item, and script data; Platinum tables are not substituted.
Source maps
Eterna, Eterna Poké Mart, Eterna Pokémon Center, Eterna Pokémon Center 2F, Eterna Condominiums 1F, Eterna Condominiums 2F, Eterna Condominiums 3F, Eterna Condominiums 4F, Eterna Herb Shop, Eterna Oak House, Eterna East House, Eterna Underground Man House, Eterna Unused House, and Eterna Pokémon Center B1F.
Version discipline
Rows merge only when Diamond and Pearl are identical, and each row carries D/P game markers. Version-exclusive species, mascot encounters, swarms, Radar slots, and GBA insertion slots keep their own labeled rows.
Route Plan
Heal and shop; talk to the Underground Man for the Explorer Kit; meet Cynthia near the statue for HM01; visit the Name Rater and herb shop as needed; inspect the Gym entrance; save Galactic HQ for after Gardenia.
- Cynthia gives Cut before the badge, but Gardenia's Forest Badge is required to use it outside battle.
- The Bicycle Shop owner remains captive until the Galactic building is cleared in the next phase.
- Professor Oak's Up-Grade gift in Eterna requires the National Dex; it is a postgame revisit, not a first-arrival reward.

Trainers
Field order follows the map's object-event order. Full teams include explicit held items and moves when trdata defines them; cash rewards use the in-engine final-party-slot level and trainer-class multiplier formula.
No trainer object, scripted battle, or assigned boss team is sourced for this section.

Puzzles, Warps, And Switches
- Gardenia waits in the Gym only after the player speaks with her outside. The Gym itself is split into an entrance map and the main forest room.
Boss Strategy And Partners
No Gym Leader, rival branch, Galactic boss, Elite Four member, Champion, story partner, or major postgame battle is assigned here.
Completion Checklist
- Complete the currently reachable part of this route plan: Heal and shop; talk to the Underground Man for the Explorer Kit; meet Cynthia near the statue for HM01; visit the Name Rater and herb shop as needed; inspect the Gym entrance; save Galactic HQ for after Gardenia.
- Review all 8 encounter rows across the per-area tables, including game markers, method band, time-of-day rates, levels, and each conditional requirement; mark conditional rows for their stated revisit.
- Defeat or deliberately skip every currently reachable trainer row; leave HM-, story-, or National-Dex-gated rows checked only after their access requirement is met.
- Collect currently reachable visible/scripted items and berry trees, use the Dowsing Machine for reachable hidden rows, and retain every explicitly gated row for the named cleanup visit.
- Resolve every currently available puzzle note, boss branch, and partner scene before opening the next section.
Sources And Validation
pret/pokediamondat commit038cccaed5de8f013875bc5d734f912d1de08e0f:map_header.c, D/P encounter archives,trdata.json, zone events, script archives, item tables, and trainer graphics.- Encounter slots were decoded from exact 424-byte D/P members and cross-checked against Gen IV slot behavior; the 0x6C pair is day, morning uses base slots, and 0x74 is night.
- Coordinates remain visible as QA anchors, while each hidden row also provides a plain-English map-region instruction.
- Generation-wide systems that are not tied to a normal map archive—Honey Trees, Great Marsh daily rolls, Trophy Garden, fossils, Pal Park, and event items—are explicitly curated in their dedicated system pages.
