One of the few rules that always worked for all Phantoms was how they got to their mission locations.
The K0-Phantoms could leave the Citadel through the gates or reach monster nests using trucks. Cases where a K0-Phantom was allowed to use a fighter were quite rare.
The stronger the Phantom became, the further away from the Citadel it hunted. This rule worked on the Upper Ring as well, but the Cave Grid was arranged completely differently from the Dead Lands; there was no need for fighters there, just tunnels that had long been dug by the Second Rank Phantoms.
Adam didn't think about this problem, but as he moved from one level to another, he felt how much longer the distances were becoming. With each level, it took 2-3 hours longer to reach the desired location.
Moreover, no one had control over the Dead Lands, where fighters could fly freely if their safety was ensured, but this did not apply to the Dark Shore and the Tarnished Lands.
