Book which has different races and could use magic

Question

I'm trying to find the title of a teenager/young adult novel I read 10-15 years ago, I've tried every keyword I could think of and searched on google but I still couldn't find it. I only could remember small bits and will try my best to describe it.

I have the picture of the novel on my phone, well at least half of the novel and the quality is potato camera kind of quality. So I can't see the name of the author clearly but I think the author name starts with WC or VC (not V.C. Andrews) and the title is LEDG... something (still can't remember and can't find it on google). Important note on the title, i read it in my native language which is Indonesian so they might change the title and that "LEDG..." wouldn't help at all but i'm 100% sure that the author is not Indonesian.

It's a magic-fantasy-war kind of novel. I think the main character was a young human male soldier, there are different races, I remember was a human-cat race(?) and maybe there was centaur race, not 100% sure though. There are magics, controlling water, fire, healing, summoning/teleporting magic, i remember the race that was summoned/teleported got green skin and considered elite race and that they bleed green. I'm not sure if every race could do magic but I remember a human-cat race controlling water on the sea and got possessed by the.. sea spirit(?).

I remember a plot where their... continent(?) were invaded by an invader from another continent across the sea, they came with tons of huge flying frigates/galleons with cannons who then bombarded cities and I think they were some kind of sea monsters race.

Answer 1

I think this is Ledgard: Musuh Dari Balik Kabut (which translates as Ledgard: The Enemy From Behind the Fog) by W.D. Yoga, published in 2005.

Ifarett's three soldiers: Nash, Rhavi, and Deedek the Centaur have a special task, which is to take Vasthi, the daughter of the leader of the Kaloon nation, back to his home. After they died, it turned out that Ifarett was devastated by the invasion of foreigners coming from the western sky on an airplane boat. One by one, the Ledgard region was devastated by the invasion of the flying boat, following Ifarett.

Nash, Rhavi and Deedek go to great lengths to convince all the nations in Ledgard that they cannot survive if they are still immersed in strife and vengeance among themselves. The risks they have to face are engaging in intrigue among the Sages, the harassing views of the inhabitants of Puri Pualam, distrust of the Ae Siri people, and the betrayal of the Centaurs.

Why did Vasthi come all the way to Ifarett just to save Nash, Rhavi, and Deedek from the invasion of the flying boat? How did the trio convince the residents of Ledgard to unite? Why did the Centaurs choose their own direction? A myriad of questions will be answered with thousands of questions in this book. Don't be curious!

I think the cover matches well, and I believe the author is Indonesian.
