The Mardan Eins is what appears on the FP chart after you catch your first Mardan Garyan. They can be found in either Muscka Racka/Lacka at dusk, or at Matataki village at night, by the waterfall. It depends on your game. They only bite poison apples. Once you catch one, the sword will appear at the bottom for 2500 FP. Once you have it, you don't build it up the traditional way. You actually build it up by catching more Mardans'. To get it to the Mardan Twie, catch 10 more Mardans'. The Arise Mardan takes another 15 of them. It did for me. The final stats of the Arise Mardan re just a bit higher than the 7thHeaven. There is only one in the game, so don't break it.
