Although it has been stated that Nintendo trademarked the names DuskGold and DawnSilver, there is no evidence showing they have. It is unknown if games with these names would be produced. DuskGold and DawnSilver seem appropriate, however, as they have similar meanings to the Ecruteak Towers. The
Tin Tower is where Pokémon come to pass on (as dusk is the end of the day) and the
Brass Tower is where Pokémon were born (as dawn is the beginning of the day). It should also be noted that these names seem backwards; the Brass Tower was home to
Ho-Oh, the
version mascot of
Gold, before it burned down, and the Tin Tower was the roost of
Lugia, the mascot of
Silver, before it moved to the
Whirl Islands. As such, DawnGold and DuskSilver would be more appropriate names. The Dusk and Dawn prefixes are, however, backed up by the introducion of the
Dusk and
Dawn stones in
Generation IV, and the fact that the
Dusk stone evolves two
Generation II Pokémon.
