Dhaos in Tales of Phantasia, specifically past Dhaos, as the whole reason he starts his war with Midgards is to prevent the development and use of magitech weaponry, which he believes will ultimately kill the planet's (rather important) world tree -- and he isn't wrong either, as Aselia is already on the way out in the present where the player starts, as indicated by the dead / dying Yggdrasill and absence of magic.
